To all; whom it may cancer/1,:

Be it known that I, MORRIS W. citizen of the U ted States,and a resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which. the following is a specification.

My invention relates more particularly to the ribbon mechanism of those machines in which type-writing as it is written is in view of the operator. In such machines, which are commonly called visible-writing .ma-

the ribbon between s is usually controlled by a which term as herein used comprehends'any device for automat- PooL, a

the ribbon-spool -ically moving theribbon, which is normally away from the printingoint, to the printing-point and for therea ter moving the ribbon away from the printing-point. Usually whenever the type-actuating mechanism is operated the vibrator is affected so as to cause the ribbon to cover the printing-point an im ression has on the platen and after been made to carry the ribbon ack to normal position, leaving the printing-point uncovered.

The continuous vibration of the ribbon-vibrator during the operation of the machine is frequently a source of annoyance to the operator. Moreover, the vibrator itself and that part of the ribbon between the spools must be lifted at each thereby increasing the amount of power which must be applied to the printing-kc s in order to effect a successful operation 0 the printing mechanism.

T he main object of the invention is to ob' viate these defects by providing a mechan ism which will cause the ribbon-vibrator to be actuated automatically to cover the printing-point and then to be retained automatically in that position during further operation of the machine either until the spacing devices are actuated or as long as may be desired.

It is to be understood that wherever it is stated herein that the ribbon-vibrator is moved to cover the printing-point it is meant that the vibrator is moved so as to cause the ribbon it carries to cover the printing-point.

Another object is to provide means to renprinting operation,

der the mechanism just des tive and to permit the vibrat mg operation, as is common.

able a two-color ribbon to be a vibrator of Another object is to provid vent the ribbon from being ing 0 eration.

Ot er objects will subse vices, and arrangements pointed out in the claims.

other kinds or styles of pivots and hangers, as desired. The' typebars are adapted to swing upwardly and rearwardly to coact with a platen 20, which is diagrammatically illusl trated and is -mounted in a carriage (not shown) which moves from side .to side of the machine across thetop plate. A carriagefeed element 21 is operatively connected with the carriage in a known manner. 1 Adapted by the centre arm 26 is a universal bar 29, which sses from side to side of the machine beneat the series of key-levers 4 and the s acing-levers 7 and 8 and is adapted to be pressed by said levers when they are suity actuated. during the operation of the machine. A spring-drum (not shown) is 0peratively connected with the platen-carria e and tends constantly to draw the latter le t-. ward across the top plate. The movement of the universal bar during printing or spacing operation causes the carriage-feeding. de-,

vices above described to cooperate in a known manner to perm1t the'carriage to move a let- :r-space in printing direction. A ribbon 30 is mounted on a pair-of ribbon-spools31, horizontally disposed, one at each side 4'5 of the machine and forward of the-platen. Each ribbon-spool is operatively connected with a which meshes with a beveled pinion 33, fixed to the frontefid of a horizontally-disposed rotary shaft 34, se-

cured to the rearend whereof is a beveledw'ith a beveled driving-pin on 36,- whichis each ribbon-spool is connected with the driv-' ing-shaft 37 by. a train of gears, as above described. 'The driving-shaft may .be shifted endwise in 'a known manner to cause one of v the other geartrains to operate and windthe ribbon 30 on its associate ribbon-spool and off the spool at the other side of the'machine.

Motion is imparted to the vibrator by an operating lever 49, fulcrumed at 50 in a lug 51 depending from the underside of the top plate. The forward end of the operatinglever is bentto form a loo or hook 52, as best indicated in Fig. 3; The loo 52 embraces or surrounds-the depending ug 42 of the vibrator. leveris'connected by anactuating member or link 58 with the arm 26. of theunive'rsalbarframe, so that by the mechanism, asexplained to thispoint, the ribbon-vibrator'will e thrown upward from normalposition to the printing-point and back again at each prmting operation, while at the same time a lon 'tudmal movement is imparted to the rib on far described 'is generally similar to butdiffers in detail from that of the Menarchtyp'e-writing machine, and it has not, therefore, been deemed necessary to describe the construction at length. it is to be understood, however, that although I have shown my invention as embodied in a typewriter resembling the Monarch machine, and although-a lar e part of the mechanism hereinbeforedescribed is to be found in saidmachine, yet nevertheless the invention may be adapted to other forms of writing-machines, and I do not desire to belimited to the particular construction and arrangement set forth and illustrated. The inner faces of the side portions 46 of the vibrator-guide 45 are formed with conical de ressions to receive the cone-like ends of a pivot-rod 54, which is sprun into place in'the side walls 46 before t e vi rator guide is securedto the machine.

A sleeve 68 is screwed on the lower end of the connecting- ,rod 65 and coacts with a fixed guide 69, se-' cured to the base 1 by a screw 70. The sleeve 68 serves to guide and steady the connecting-rod 65 as it 'is reciprocated in operation. The left arm 66 of the member 66 is ordinarily so positioned that it will be actu: ated by the spacing-lever 7 when the latter is depressed, while the right-hand arm 66 of the contact member 66 is adapted to be actuated by a special key-lever 71, which is pivoted at 72 to a lu 73, secured tothe machine-base. Pivots at 74 to the free end of the special key-lever 71 is a ke -s teI'n 75, terminating at the top in akeyu'tton 76and at the lower end ma hook 77. A checkspring 78 is secured as most clearly seen in-Fig. 7, by a screw 79 and is adapted to coact with notches 80 in the key-stem 75 so as to maintain the latter mpredeterrnined positions,- in one of which the hook 77 will cooperate with an abutment 81, fixed to the base ofthe machinev i Referring now to Fi s. 3 and 5,it will be noted that the outer member 661's bifurcated.

posed, and it wi en of the arm 66? of the which is (pivoted at 84 to a-fixed lpart of the base an extends outwardly t rough an opening in the side of the latter, terminating in a finger-piece 85. A spring-positioning member 86, fixedly secured at 87, 1s provided with flutings .or corru ations, 88, said corrugations being adapte to receive the outer the member 86 being thereby adapted to maintain the lever 83 in either of a plurality of predetermined positions.

When the parts are in normal position, the looking or retaining member 55 is pressed lightly against the back of the ribbon-vibrator by the, spring 56, the relations of the parts being indicated in Fig. 1. Thus positioned, whenever a printing-key 4 is de ressed the y about its atmg-lever49 to throw the ribbon-vibrator upward until the ribbon 30 covers the printing-point on the platen, whereupon the notch 57 in the ribbon-vibrator is engaged by the looking or retaining I member 55. Consequently when under the influence of its restoring-spring (not shown) the universal bar starts to 'return to normal position, carrying with it the link 53 and the operatinglever 49, the ribbon-vibrator, under the influence of the retainin member or detent 55, ree printin -point, so that the hooked portion 52 of t e operating-lever moves downward away from the shoulders 41 of the vibrdtor. The vibrator will now be positioned as indicated in Fig. 4 and during immediately succeeding operations of the printin -keys will serve as a fixed ribbonguide t ough which the ribbon is fed longitudinally across the face of the platen at the rinting-point. When the end of the word being written is reached, or when for any other reason it'is desired to move the carriage a letter space without printing, the spacing-bar 11 is depressed, thereby swinging downward the spacing-levers 7 and 8. As the spacing-lever 7, moves downward it deresses the arm 66 of the member 66, therey lowering the-connecting-rod 65, which rocks the rock-shaft 62 so as to-cause the crank-arm or detent-releasing member 61 to press the crank-arm forwardly and swing the retaining member 55 against the pressure of its spring 56 away from the notch 57 in'the detent 55," the ribbon-vibrator is at once drawn downward by the draw-spring'58 until the shoulders 41 contactwith the hook portion 5201 the operating-lever. By this operation ofthe spacing mechanism it will be noted that the rinting-point is again exll remain exposed until the printing operation is resumed. If after the vibrator has been movedto the printingapoint and While it is retained thereat, asin cated in Fig. 4, it be desired to ex- Freed from the member or .vibrator m ay pose the printing-point without causing a letter-space movement of the carriage, the special key-lever 71. is depressed. Asit swings downward, it will act upon the arm 66" of the contact member 66 so as to move the connecting-rod 65 downward, thereb causing the parts to cooperate to free the v1- brator from the retaining means in the manner above described. The special key and the other parts of the unlocking mechanism up to and meluding the crank-arm 61 will be restored to normal position by the restoringspring 62. From an inspection of Fig. 3 it will be noted that the special key 71 is to the right of the universal bar-29, so that the deression of said special key will not ailect the otter-spacing mechanism, and the carriage will therefore not be moved, but such depression of the special key will move the contact member 66 out of the path of the spacinglever. 7, so that the latter cannot operate the link 65 while the special key 71 is maintained depressed.

If after the ribbonvibrator has been automatically moved to the printing-point and while it is automatically retained thereat in the manner above described to serve as a fixed ribbon-guide it be desired to space between words or to use the spacing mechanism for any other pur ose without affecting the ribbon-vibrator tiis result may be accomplished in the following manner: The lever by means of the finger piece 85 is swung from the full-line position indicated in Fig. 3 to the dotted-line position in said figure, thereby causing the de endin stud 82 to coact with the bifurcate end 0 the arm 66 to rotate the member 66 about the connecting-rod 65. As indicated by dotted lines in said Fig. 3 this rotary movement swings the arm 66 rearwardly out of the plane of operation of the s acing-lever 7 so that when the spacing mec ianism is thereafter actuated the ribbon-vibrator will not be affected, but will remain motionless at the printing-point With the contact member 66 positioned as last described the ribbonbe disconnected from its latch and restored to the position indicated in Fig. 1 at any time by actuating the s ecial-key mechanism. Upon swinging the handle 85 forwardly again the member 66 may be restored to the full-line position, Fi 3, so that the vibrator may be again unlatched by either of the described means.

If at any time it is desired to cause the vibrator to move to and from the printing point at each actuation of a printing-key, this result i my be attained byfirst depressing the key -button 76 and then pulling it forward until the hook 77 engages with the fixed abutment 81, asindicated in Fig. 6. This operation, as-will be noted from an inspection of said figure, causes the crank-arm 61 vto remain taming stored in a manner in enga ement with-the crank-arm 60, there- 65 by holding the retaining member 55 away from the ribbon-vibrator, so that the latter ma be vibrated at each printing operation wit out bein affected b the looking or rem'echanism. T e key-button 76 may be swung forward at any time, thereby permitting the parts to act as before.

In the modified construction illustrated in Figs. 8 and 9 the rear face of the central portion 40 of the vibrator is provided, in addition to the notch 57, with a second notch 57 below and in the same plane with the first notch. The ribbon 30 shown in these views is rovided with two longitudinal stripes or elds cc and g, which are preferably colored black and red, respectively. When a printing-key is operated, the vibrator will be thrown upward, ashitherto described, until the retaining member 55 engages with the notch 57, thereby so positioning the vibrator at the printing-point that the t pes will cooperate with the black field :1: 0 the ribbon, and during the operation of the arts, as hitherto described, the printing wil always be done on the field at or black field. Fre- -quently it is.desired to write a word in red in the body of matter ty e-written in black, and this may readily e accomplished by manually moving the vibrator upward when the notch 57 is engaged by the retaining member until the second notch 57 engages with said member. The arts will then be positioned, as indicated in i ig. 9, with the red field y of the ribbon opposite the printingpoint, so that the nex't'word written will ordinarily be in red. When the space-bar is actuated, the parts will be automatically rehitherto described to the position indicated in Fig. 8, so that the next succeeding type-impression will bein black, thusautomatically chan ing from the red field to the black field. f several words or lines of type-writing are to-be written in red, it is only necessary torender the s acing mechanism inoperative to release" t e vibrator from the rinting-point and thereafter to maintain tl ie spacmmechanism thus inoperative as long as it is esired to print in red.
